2014-03-14perf bench: Add futex-hash microbenchmarkDavidlohr Bueso
Introduce futexes to perf-bench and add a program that stresses and measures the kernel's implementation of the hash table. This is a multi-threaded program that simply measures the amount of failed futex wait calls - we only want to deal with the hashing overhead, so a negative return of futex_wait_setup() is enough to do the trick. An example run: $ perf bench futex hash -t 32 Run summary [PID 10989]: 32 threads, each operating on 1024 [private] futexes for 10 secs.

2014-03-14perf bench numa: Make no args mean 'run all tests'Arnaldo Carvalho de Melo
If we call just: perf bench numa mem it will present the same output as: perf bench numa mem -h i.e. ask for instructions about what to run. While that is kinda ok, using 'run all tests' as the default, i.e. making 'no parms' be equivalent to: perf bench numa mem -a Will allow: perf bench numa all to actually do what is asked: i.e. run all the 'bench' tests, instead of responding to that by asking what to do. That, in turn, allows: perf bench all to actually complete, for the same reasons. And after that, the tests that come after that, and that at some point hit a NULL deref, will run, allowing me to reproduce a recently reported problem. That when you have the needed numa libraries, which wasn't the case for the reporter, making me a bit confused after trying to reproduce his report. So make no parms mean -a.

2014-03-14irqchip: sun4i: Don't ack IRQs > 0, fix acking of IRQ 0Hans de Goede
All IRQs except for IRQ 0 seem to not need acking, so drop acking for them. The ENMI needs to have the ack done *after* clearing the interrupt source, otherwise we will get a spurious interrupt for each real interrupt. So use the new IRQCHIP_EOI_THREADED flag for this in combination with handle_fasteoi_irq. This uses a separate irq_chip struct for IRQ 0, since we only want this behavior for IRQ 0.

2014-03-14irqchip: sun4i: Fix irq 0 not workingHans de Goede
SUN4I_IRQ_VECTOR_REG containing 0 can mean one of 3 things: 1) no more irqs pending 2) irq 0 pending 3) spurious irq So if we immediately get a reading of 0, check the irq-pending reg to differentiate between 2 and 3. We only do this once to avoid the extra check in the common case of 1) hapening after having read the vector-reg once.

2014-03-14genirq: Add a new IRQCHIP_EOI_THREADED flagThomas Gleixner
The flag is necessary for interrupt chips which require an ACK/EOI after the handler has run. In case of threaded handlers this needs to happen after the threaded handler has completed before the unmask of the interrupt. The flag is only unseful in combination with the handle_fasteoi_irq flow control handler. It can be combined with the flag IRQCHIP_EOI_IF_HANDLED, so the EOI is not issued when the interrupt is disabled or in progress.

2014-03-14x86/amd/numa: Fix northbridge quirk to assign correct NUMA nodeDaniel J Blueman
For systems with multiple servers and routed fabric, all northbridges get assigned to the first server. Fix this by also using the node reported from the PCI bus. For single-fabric systems, the northbriges are on PCI bus 0 by definition, which are on NUMA node 0 by definition, so this is invarient on most systems. Tested on fam10h and fam15h single and multi-fabric systems and candidate for stable.

Pull networking fixes from David Miller: "I know this is a bit more than you want to see, and I've told the wireless folks under no uncertain terms that they must severely scale back the extent of the fixes they are submitting this late in the game. Anyways: 1) vmxnet3's netpoll doesn't perform the equivalent of an ISR, which is the correct implementation, like it should. Instead it does something like a NAPI poll operation. This leads to crashes. From Neil Horman and Arnd Bergmann. 2) Segmentation of SKBs requires proper socket orphaning of the fragments, otherwise we might access stale state released by the release callbacks. This is a 5 patch fix, but the initial patches are giving variables and such significantly clearer names such that the actual fix itself at the end looks trivial. From Michael S. Tsirkin. 3) TCP control block release can deadlock if invoked from a timer on an already "owned" socket. Fix from Eric Dumazet. 4) In the bridge multicast code, we must validate that the destination address of general queries is the link local all-nodes multicast address. From Linus Lüssing. 5) The x86 BPF JIT support for negative offsets puts the parameter for the helper function call in the wrong register. Fix from Alexei Starovoitov. 6) The descriptor type used for RTL_GIGA_MAC_VER_17 chips in the r8169 driver is incorrect. Fix from Hayes Wang. 7) The xen-netback driver tests skb_shinfo(skb)->gso_type bits to see if a packet is a GSO frame, but that's not the correct test. It should use skb_is_gso(skb) instead. Fix from Wei Liu. 8) Negative msg->msg_namelen values should generate an error, from Matthew Leach. 9) at86rf230 can deadlock because it takes the same lock from it's ISR and it's hard_start_xmit method, without disabling interrupts in the latter. Fix from Alexander Aring. 10) The FEC driver's restart doesn't perform operations in the correct order, so promiscuous settings can get lost. Fix from Stefan Wahren. 11) Fix SKB leak in SCTP cookie handling, from Daniel Borkmann. 12) Reference count and memory leak fixes in TIPC from Ying Xue and Erik Hugne. 13) Forced eviction in inet_frag_evictor() must strictly make sure all frags are deleted, otherwise module unload (f.e. 6lowpan) can crash. Fix from Florian Westphal. 14) Remove assumptions in AF_UNIX's use of csum_partial() (which it uses as a hash function), which breaks on PowerPC. From Anton Blanchard. The main gist of the issue is that csum_partial() is defined only as a value that, once folded (f.e. via csum_fold()) produces a correct 16-bit checksum. It is legitimate, therefore, for csum_partial() to produce two different 32-bit values over the same data if their respective alignments are different. 15) Fix endiannes bug in MAC address handling of ibmveth driver, also from Anton Blanchard. 16) Error checks for ipv6 exthdrs offload registration are reversed, from Anton Nayshtut. 17) Externally triggered ipv6 addrconf routes should count against the garbage collection threshold. Fix from Sabrina Dubroca. 18) The PCI shutdown handler added to the bnx2 driver can wedge the chip if it was not brought up earlier already, which in particular causes the firmware to shut down the PHY. Fix from Michael Chan. 19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as currently coded it can and does trigger in legitimate situations. From Eric Dumazet. 20) BNA driver fails to build on ARM because of a too large udelay() call, fix from Ben Hutchings. 21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix from Eric Dumazet. 22) The vlan passthrough ops added in the previous release causes a regression in source MAC address setting of outgoing headers in some circumstances.

2014-03-13staging: rtl8188eu: explicitly convert from __le16 to integerKristina Martšenko
BA_para_set (of type __le16) is implicitly cast into an integer for bitwise operations, after which the result is converted back into a __le16. Make the initial cast explicit to make the code clearer. In addition, refactor the code for readability.

2014-03-13x86_32, mm: Remove user bit from identity map PDEAndy Lutomirski
The only reason that the user bit was set was to support userspace access to the compat vDSO in the fixmap. The compat vDSO is gone, so the user bit can be removed.

2014-03-13x86, vdso: Remove compat vdso supportAndy Lutomirski
The compat vDSO is a complicated hack that's needed to maintain compatibility with a small range of glibc versions. This removes it and replaces it with a much simpler hack: a config option to disable the 32-bit vDSO by default. This also changes the default value of CONFIG_COMPAT_VDSO to n -- users configuring kernels from scratch almost certainly want that choice.
